HP Operation
Orchestration OO provides a comprehensive solution to Automate incident resolution, change orchestration
and routine maintenance tasks in your data center. HP Matrix OE with infrastructure orchestration
has an embedded version of OO to take advantage of the OO workflow engine capabilities.

Manager SPM, the software application described in this document.
I
initiator An endpoint that consumes storage through a storage area network. These storage consumers
initiate storage actions.
L
logical disk A partition or logical disk that may contain a file system or database or be used by a volume
manager or hypervisor to present higher order volumes. Volumes are backed by capacity that
has been carved from lower level capacity meaning that the source of the capacity has been
identified. In SPM a volume is a type of service.
See also volume.
logical unit The entity within a SCSI target that executes I/O commands. Each logical unit exported by an
array controller corresponds to a volume.
logical unit number A LUN is an address used in the SCSI protocol to access an array within a target. In the case of
SPM, a LUN refers to a volume that has been presented to one or more initiators. SPM also
supports unpresented volumes which have been created but do not have LUNs.
M
HP Modular Smart
Array MSA is a direct attach, external shared storage solution that helps customers easily transition
from direct attached to centralized storage. It enables departmental and small to medium businesses
customers to grow capacity as demands increase.
N
network Technology agnostic term used by SPM to refer to FC based SANs, Fabrics, or IP based SANs.
nonconformant Within SPM, services are nonconformant if and only if at least one of the requirements that defines
the service is not satisfied. Open network -- FC networks that do not have zones are said to be
open.
P
physical capacity The maximum amount of storage available on an array or pool, as constrained by the physical
structure of the device.
provision Within SPM, to provision a service is to discover resources that fulfill the requirements of that
service, and to assign those resources to the service.
proxy A world wide name in a Fibre Channel network that is used to identify the network to which an
unknown initiator belongs.
Q
quarantine Within SPM, a quarantined resource is a resource that will not be used to fulfill the requirements
of a storage service. Resources can be placed into quarantine by SPM during recovery, or they
can be manually placed into or taken out of quarantine by an administrator.
R
RAID A Redundant Array of Independent Disks is a RAID. A RAID volume consists of more than one
drive, but appears to the operating system to be a single logical disk. RAID improves performance
by disk striping, which involves partitioning each drive's storage space into units. By placing
data on multiple disks, I/O operations can overlap in a balanced way, improving performance.
